Cmuicctirut, have, 'invented zin.improvement in Vehicle-Springsy of which the following is n, specification.

This invention has for. its,l object to pro-- d ucc u. spring :u'lupted for general 115e upon all kinds oi Vehicles und especially adapted for use upon motor cnrs und trucks, and which is adapted to be used independently of or in connection with othe' springs', or su; z. shock absorber, thc osfscntiul feature of which is that u Suuponded pni--.uumftic cushion 'iu cminection with guide tubos and pluuger is substituted for the variouss types ot uietullic :springs now in use,thus enabling the builder to save room in the vchicle und to )rovidc un cxceedinolv eus f riding suine' b tu tu having ull the :tlvui'itgjes of high grad pneumatic tiros` und which, in niuny instances Willmalte the usc oil1 pneumatic tireo` uw necessary., thereby cll'cixting :in iniportunt sawing in both the initial cost und the ruuning cout olf motor :urs und trucks.

ln the accompanying drarsiilu toruiingj r .D port oi Athis specification, Figure 1: is an ole- Yation illustrating .the uwplfilication of mi' iovel spring to un uxle which iuliown in section; Fig'. 2 i Section on the line 2&2 in lig, 1,-looliing' in the direction of' the urrows; und Fig. 3 if; a section on thc line l--3 in Fig. 1, `loo'ling` in the direction of the arrows. i

.ll/ly novel 'Spring comprises :1` rest suspended :from the axle, a pneumatic cub'hion car-- iied l)V7 the rest which su D )orte the weioht und guide tubes und pluugerfs carried rcspectively by tlie'uxle und the cushion.

10 denotes un axle which passes throughl ol' tho special torni illustmted,L that is a.

cushion resembling in shape u seg'iucnt ol uu ordinary piiiefunmtic tire sind which may be constructed upon. the principles corninonlyin use in pneumatic tires.. lt should be rude stood, however, that :my other Tibo-rui of pneunnticcushion may he used iig-preerrcd, thoreutof course being shaped to correspond with the cushion :it has to furry.

17 denotes n plate which 'restes' upon the cushion und corresponds Withl the shape thereoil und is connected tro the platform by suitable supports :is 18. lVhore a segmentsliziped cushion is used t preferably support the ende of the cushion by ring-5 1t)4 lwhich are cust integrul with or rigidly sccured to the pleite.. und support and incluse the ends of thcushion'.

El@ denotes guide tubeel open ut their upper ends which :irc carried by and depend from top pluto 13. und 21 denotes plungers which are rigidly Sccured'to find depend 'l'rom the platform und llt closely'r in the guide tubes, but are short Qnough so tiuit under no cir-- ciuinstzinces con' the" ends ot lthe ylung-ers come in contuct with the lower cnds Aof the `gui/do tubc. V'lie ends of the `guide tubes are provided ufitlroue or more air holes, 'ndiczitud by il? which permit the :tir to be 'forced out of the guide tul'icsslouly by the downward movements of the plungew :1nd eijiecizil'ly to hednivn inward slowly, thereby retarding the upward movements oit' the plungers, as will be more fully explained.

The: opcration will be' obvious trom the drawing. The .rest is rigidly supported troni th Yuxle und carries the. cushion, which iu turn currieri the platform und the weight. Sirsiyiug or the lliod); of u `caror tr ich, or whateier parte may be carried by the plutlorm, in :my direction, Wholly prevented by the guide tubes and plungcrs, the ruine tubes beingI carried by the axle und 'the ptungcrs by the platform; lt will be neen, therefore, that the only movement of 'the platform permitted isi u Vertical movement. ll \\".iu'u1d--r'ioveuients of the plattform :irc tzilen up bjr-thepneumatic cushion :lud also by thc resistance of the nir in the. guide tubcs which is forced out through holes 22 relatively slowly by the' Aiiluiigers. The guide tubes and plungers perform an addr tional 1und ver); important function iu that 'claim bo): provided they retard the upward movement of-'tiie piangere end consequently of 'tbe platform as partir/l Vacuums are created under the plungers when their upward movement conimeimes, 'which can only be filled reletively slowlyby the entrance of air throughA holes 22. The functions of the guide tubes and piangere are therefore in addition to preventing any swaying movement of the body or parts carried by the platform to assist in absorbing the vshoek'o" downward iiioi/enients of the platform and to absorb' 'the shook of upward movements by retarding them through the relat-ii-ielyV slow entrance of air into the guide tribes.

Having fstrietingtlie adniission and discharge of ai?- tllei'efroiii, a platform provided wit-li a plate that' seats on' tbe by the platfornrand slidable in the gareeube.

thus' describedl my invention It A Cushion', and a pluri-i @sassi 3. A vehicle spring comprising an axle bo L A vehicle spriirg` comprising an axle box provided with a cushion rest, seid box being also provided with guide tube, said tube being provided with means for retarding the admission and exhaust or" air to create a partial vacuum therein, a Cushion seated on tbe rest, a platform having a plunger that is slidable in the guide tube, and cushion-engaging means carried by tbe pla tforin.
